re: #37 A Three Hour Tour
It sounds like you’re describing a sound that falls somewhere between a “sh” and a “ch.”
It’s like trying to make the ch sound in “Bach” and also leaving the C silent at the same time. I’m sure there’s a word for this in linguistics, but I don’t know it. It’s just different enough from a full ch or kh to stand out like a sore thumb to me when I hear it.
